curl: Protocol Smuggling / CRLF Injection via Gopher Protocol allows Arbitrary Command Injection

Summary: I have discovered that the Gopher protocol implementation in curl fails to properly sanitize newline characters %0d%0 in the selector path. This allows an attacker to inject arbitrary TCP commands when curl connects to a target server via gopher://. This vulnerability enables Protocol...

curl: Integer Overflow in `curl_easy_escape()` may lead to heap buffer overflow and stack memory disclosure on 32-bit platforms

Disclaimer Both the confirmation, and reporting of this vulnerability used AI assistance. Nonetheless, I manually reviewed all of the reported results, including its reproduction steps and source code. Summary The curleasyescape function in lib/escape.c contains an integer overflow vulnerability...

Command Injection via Malicious Model Artifacts

A command injection vulnerability exists in MLflow's model serving container initialization code. When deploying a model with envmanager=LOCAL, MLflow reads dependency specifications from the model artifact's pythonenv.yaml file and directly interpolates them into a shell command without...

MLflow Tarfile Path traversal in mlflow/mlflow

Description Vulnerability Report: Unsafe Tar Extraction Path Traversal Due to the lack of path traversal verification in the tar decompression part, it may lead to the possibility of overwriting any file or gaining elevated privileges. This is a non-expected vulnerability. Location File:...

LinkedIn: Session Cookie Leakage via Static Header Field in WebViewerFragment

A vulnerability was identified in the "WebViewerFragment" that could lead to the leakage of the user's cookies. The root cause was a static field "CUSTOMHEADERS" that persisted cookies across different URL loads, allowing an attacker to steal the victim's session cookies. The vulnerability was...

curl: HAProxy Connection Reuse leads to IP Spoofing and mTLS Context Smuggling

Executive Summary libcurl fails to respect the CURLOPTHAPROXYCLIENTIP configuration when reusing existing connections. Due to a missing check in the connection pooling logic, libcurl indiscriminately reuses a TCP/TLS connection established with a specific identity IP A for subsequent requests...

curl: Public-suffix cookie injection when libpsl is disabled

Summary: When libcurl is built without libpsl, Domain attribute validation accepts public suffixes like .co.uk, allowing a malicious host to plant cookies that are later sent to unrelated sibling domains using the same cookie jar. AI assistance was used to draft this report. Steps to Reproduce: 1...

curl: libcurl WebSocket handshake accepts any Sec-WebSocket-Accept

Summary: libcurl upgrades to WebSocket without validating Sec-WebSocket-Accept, allowing a spoofed 101 response to complete the handshake and inject frames; AI assistance was used to draft this report. Steps to Reproduce: 1. Clone and build curl from source: git clone --depth=1...

Node.js: TLS PSK/ALPN Callback Exceptions Bypass Error Handlers, Causing DoS and FD Leak

A flaw was discovered in Node.js TLS error handling that allowed remote attackers to crash or exhaust resources of a TLS server when pskCallback or ALPNCallback were in use. Synchronous exceptions thrown during these callbacks bypassed standard TLS error handling paths, causing either immediate...

Apache Arrow IPC cached prebuffer path triggers signed integer overflow UB in read-range coalescing

Description Apache Arrow C++ commit d89c14b5d5203bc403fb62060fdf1ef2c0a49339 contains a signed integer overflow undefined behavior in the IO range coalescing logic, specifically in arrow/cpp/src/arrow/io/interfaces.cc:475 arrow::io::internal::CoalesceReadRanges. The overflow is reachable from...

curl: Functional Regression in Digest Authentication: Failure to handle optional spaces and escaped quotes

Summary A recent migration of the Digest authentication parsing logic to the curlxstr strparse API introduced two functional parsing regressions in lib/vauth/digest.c. 1. Optional Whitespace OWS Handling The current implementation fails to skip optional whitespace after comma delimiters in...

curl: A logic error in detect_proxy caused truncation of environment variable names for long protocol schemes.

In lib/url.c, the detectproxy function uses a fixed-size buffer, proxyenv20, to construct proxy environment variable names e.g., httpproxy. However, the curl URL parser lib/urlapi.c allows protocol schemes up to 40 characters MAXSCHEMELEN. When a protocol scheme longer than 12 characters is used,...

Rocket.Chat: Unauthenticated SSRF in Voxtelesys integration ('checkUrlForSsrf' Bypass via DNS rebinding)

An SSRF vulnerability was discovered in Rocket.Chat version 7.13.2 that was caused by a DNS rebinding attack. The vulnerability allowed an attacker to bypass a security check and access internal hosts on the same network as the Rocket.Chat server. The vulnerability was present in the SMS...

curl: Unbounded memory consumption via compressed HTTP responses (gzip/brotli/zstd)

During a review of curl's handling of response decompression, it was noticed that no limit exists on the final uncompressed data volume from compressed HTTP replies. Instead of setting constraints, the current design allows indefinite expansion during processing. This absence of limits could lead...

curl: Heap buffer overflow in Curl_ipv4_resolve_r due to incorrect buffer alignment and size calculation on AmigaOS

Summary: A heap-based buffer overflow exists in the AmigaOS-specific DNS resolution function Curlipv4resolver located in lib/amigaos.c. The function uses gethostbynamer with a fixed-size heap buffer CURLHOSTENTSIZE and performs incorrect pointer arithmetic when calculating the data buffer offset...
